may be provided on its periphery with rubber, as at Z,1f so desired.

The sound box l? may be of any suitable construction and may have an adjustable rotation on a horizontal in the end of the tubular arm E so as to be able to turn the stylus up or down with respect to the record tablet, to permit the changing of the .record tablets and also to bring the stylus into normal adjustment. A spring j' may be employed for holding the stylus point in contact with the record tablet or elevated from the same according as to the adjustment of the sound box whether tor playing or when changing the record tablets.

The operation of my improved machine will now bc understood: The machine being in the position shown in Fig. 1, and having just completed the reproducing of sound from a record tablet, the stylus of the sound box is turned upward by rotating the sound box, the record tablet D is removed and a new record tablet is placed in position. The motor is then put into operation. '.lhe sound box'is then rotated into position to bring the stylus into contact with the record groove of the tablet. By the combined rotation of the feed screw J and the driving wheel L, the turn-table is rotated and at the same time its axis of rotation 'i is shifted longitudinally with respect to the sound box and stylus4 so that the surface speed otl travel of the record groove under the stylus remains substantially constant. This continues until tle record tablet has been, together with the turn-table, shifted to bring the end of the record groove under the stylus and which has completed the reproduction of the sound from the' record groove of that particular tablet. The lever J2 is then depressed and the carriage I and turn table pulled again to position shown in Fig. l and a new record disk tablet substituted for that from which sound was before reproduced.

The result of reproducing sound from a record tablet in' the manner herein referred to, namely one in which the record groove is so formed and the machine so operated that uniform or constant speed of travel of the record groove under the stylus is insured, results in a more perfect articulation or production of sound than where the surface speed of travel of the record groove is constantly varying as in the case of the gramophone instruments as they are commercially constructed and operated. It will be seen, however, that an ordinary gramophene record tablet would not be suitable tor use in a machine of the character herein described because the speed of travel of thel tuin-table carrying the record disk is constantly changing and hence would cause the' While the construction shown is excellently adapted for the purposes of my invention, l do not confine myself to the details, as these may be-considerably varied without departing from the principles of my invention.

Having now described my invention, what l claim as new and desire to secure by Letters Patent, is:

l. ln a machine for yreproducing sound, the combination of ay rotating turn-table for the sound record tablet, a sliding frame in which the turn-table is ournaled on a vertical axis and by which it may be shifted, mechanical feeding devices for feeding the sliding frame uniformly, power mechanism for directly rotating the turn-tableindependently of the feeding devices, means attached to the sliding frame for simultaneously disconnecting the turn-table from the feeding devices and from the power mechanism which rotates it and provided with an extension forming a handle by which the frame may be moved when freed from the feeding mechanism, a sound box, and a i'iXed support above the turn-table in which the sound box is journ'aled.

2. In a machine for reproducing sound, the combination' of a rotating turn-table for the sound record tablet, a sliding 'trame iu which the turn-table is journaled and by which its axis may be shifted, mechanical feeding devices for feeding the sliding frame uniformly, means extending beyond the turn-table for mechanically connecting the sliding frame with the feeding devices or disconnecting it therewith and directly moving the sliding frame independently of the feeding devices, a fixed frame arranged above the turn-table, and a sound box having a tubular part journalcd in the fixed frame on an axis parallel to the turn-table but to one side of the plane of travel ot" the axis of the *aufn-rabia and having the :zyhis point Subs'nriaiiy constant, and means "or cmiarrmiged to make 'coiifmt with ih@ record metil or discoiiiiecing h@ i rabia with abiet upon lie turn-table nppiozimiiely iii 'die menig for iiwviii( the, turnhe verical piane of ik@ trawl 0i' the axis ui tab? toward the 50mm box. the turn-'tabla achille 'for rapizxiwing sm in a machine for repmduuizig sound, "501i or' a turirirbis for Hw i *die coiiibiimtion nf a furia-rabia for thr relatively s'tzriioiiarv sonni record whim, a sliding fram@ rpoii which sans iiidepei'ufeiit or iii@ ii rh@ turn-tubi@ is journaied, a ,staioi fading means ffii' slowly fr 'i0 Drucker tending over die slid-ir if 'the turn-tz @wird "die 7 an@ turn Able amid provided Wim l ns for rotating the urnfably passage above the hiru-table termina'rixig at zz speci W'iiich gradually "varies A creone and in an upright @peiling and at the bv the surface speed of travel of 'rhs om oher end iiia horizontal opciiiig a sound groove he abet under the styus mii boi; rotatably gjourimie in the ilorizoiiul sutfsai'i'fiaiy @Gush/mt, uid means for Siim opening of ik@ bracket and 'iwih irs iiummousiy arresting the. roaion hragm at ri ht ano-ies io 'the l ne (if rmf'el s bis :ma wir discoziiiectm i L c .i
